Battle.net shows me online even when im not

After installing the battle.net app on my mobile I am always online/away instead of offline in battle.net friend list for others when I shutdown my PC. It even shows me online/away even if I log out of Battle.net app on phone. Please fix this. I don’t want to appear always online.

Edit: I uninstalled the app and I still appear to be online with mobile … Blizzard please.
